There is something for everyone to like this morning. Twitter founders and employees made money. The original investors made money. And if you believe Twitter has growth and profits in its future, then lots of people who wanted to buy a share got in at a fairly reasonable price. Tech reporter Scott McGrew reports.

A Bay Area girl who sells lemonade in the name of ending slavery across the globe was asked to ring the bell at the New York Stock Exchange Thursday morning as Twitter went public.

"If you can dream it, you can do it," Vivenne Harr of Fairfax, Calif., tweeted from her @MakeAStand account. "From a lemonade stand to the bell podium. You can do anything."

She later told NBC Bay Area through her father that she rang the bell for "hope and freedom," and she wanted enslaved children to hear it, too, because "this is for them."

That the fourth grader was invited to the opening wasn't a surprise, said Make a Stand spokesman Alex Campbell. That she got to actually ring the bell, wearing a Twitter-blue tutu, along with a Boston police officer, and Star Trek actor Sir Patrick Stewart by her side, was definitely a shocker.

When the bell sounded, the bubbly blond girl raised her fists in the air and gave a high-five to those standing next to her. The stock started trading at $45.10, and was considered a "blockbuster" on Wall Street. Vivienne didn't have to miss school for the big debut. This year, her dad said she is being "worldschooled."

Vivienne has been making headlines since August 2012, when she vowed to sell lemonade for 365 consecutive days and donate all the money to end child slavery.

She surpassed that goal, raising more than $100,000 in that time. She has now started a socially conscious company with her father, Eric Harr, a triathlete, author and co-founder of Resonate Social, a successful digital marketing company, which he sold to run Make A Stand Lemon-Aid.

Campbell said that Twitter has purchased her organic, fair trade, "tunnel pasteurized" lemonade to serve its employees.

And when she wasn't hobnobbing with Twitter execs and movie stars, she was being a big older sister, watching over 4-year-old brother, Turner, who also helps her make their mother's original lemonade recipe.

The elder Harr is big on social media and uses Twitter regularly, including a Storify he created, showing Vivienne touring the San Francisco headquarters in October, and employees gushing about what an honor it was to meet such an honorable young lady.

Harr told NBC Bay Area that his daughter was invited to ring the bell because the Twitter execs told him: "This is just how we want the world to use Twitter."
